It is NOT the same pump for the front and rear wipers.
The two pumps are very close physically - same size, same plastic housing to attach to the reservoir, but have different electrical connectors. If you want to just remove and replace plug and play you will likely need to visit the Stealership.
The generic pump from the auto store(s) in my town had you LEAVE the seized OEM pump in place, then graft a couple of hoses to it and daisy chain the new pump to the old as the OEM pump has a 3/4" or so input press fit into the reservoir. You also would need to splice the wiring for power. This felt awfully ghetto and prone to failure. (says the guy with rubberized undercoating on his quarterpanels etc.)
I didn't like that idea since the space is tight up in the fender, I don't run fender liners which lets all sorts of roadwash up there, and I didn't wasnt to just zip tie a pump up there and hope it stayed. So I paid around 75 bucks for a MOPAR pump.
I checked and polizi212 is quoting an OEM style pump, (stupid Canada and our limited, yet high priced selection) I spent a week returning generic pumps, GRAND cherokee pumps, and finally buying a dealership pump for my '00 XJ.
HOWEVER: Before you replace any pump with any other pump, pull the upper pump from the reservoir (don't let the grommet fall into the reservoir or you will be removing the whole thing - ask me, I know) and test it with a couple small pieces of wire and your battery. If the pump whirrs it's fine, mine just did nothing. It is possibly the switch is busted in the dash. My switch is kind of broken - if you toggle it to wash it will spray and do the three sweep pass, but left on it doesn't have a 'delay' sweep anymore.
